    CRichEditCtrl - where's the cursor?

    I've added a "row, column" pane to the status bar of my frame wnd.
    When the rich edit ctrl receives the selchange notification, I'm determining what the selection is and updating the pane. My problem is that GetSel() always returns the left most selection as min and the right most selection as max and I'm determining the column by calc'ing the (cpMin - LineIndex()). Obviously if the user has selected text toward the right, the cursor will be at the cpMax position, but I'm still retrieving the row from the beginning of the selection.
    Do you have any ideas about how I can go about determining where the cursor itself is within the selection (either at min or max)? Or a better way to retrieve the current row of the cursor?

    Thanks bunches yo.

    No, I don't at first glance. Why do you need the current cursor posistion in a selection anyways?

    Hehe. In a pane on the status bar I am displaying the position of the cursor in the current document (ie: "Ln 1, Col 10" means the cursor is in the first row in the tenth column.
    I update this text every time the selection changes (which is basically whenever the cursor moves). The only way I can figure to determine the column of the cursor is to GetSel(). However, GetSel() returns the selection independent of the location of the cursor. So if I hold down shift and arrow to the right, the column will not change from the left end of the selection.
    Does that make any sense?

    So, again, I need a way to determine definitely what column the cursor is in.

    Hey codeplug, what does "gg" stand for? "Good game" or something?

    Sometimes I don't see the forest for the tree's (or something like that).

    Try GetCaretPos(), and read the Carets Overview.

    "gg" are my initials in rl

    You can use the EM_CHARFROMPOS message to translate the client coordinates of the caret posistion into a character index. I don't think CRichEditCtrl has a front-end for that message.

    Thanks gg. Big help, as always.
